The stability of (Mg, Fe) SiO3 perovskite in the deep lower mantle has long been uncertain.
Recently, a phase transition from perovskite to postperovskite was discovered through a …

The discovery of the postperovskite (PPv) transition has profound impact on our
understanding of the core-mantle boundary (CMB) region. Unlike perovskite (Pv), the PPv …

High-resolution x-ray diffraction and scattering is a key tool for structure analysis not only in
bulk materials but also at surfaces and buried interfaces from the sub-nanometer range to …

Polycrystalline MgGeO3 post-perovskite was plastically deformed in the diamond anvil cell
between 104 and 130 gigapascals confining pressure and ambient temperature. In contrast …

The first experimental studies on minerals and rocks under high temperature and high
pressure were probably carried out by Sir James Hall (1761–1832). At that time, some …

Abstract 2D halide perovskite‐like semiconductors are attractive materials for various
optoelectronic applications, from photovoltaics to lasing. To date, the most studied families of …

Phonon dispersions and vibrational density of states of MgSiO3 postperovskite, the new
high‐pressure phase of MgSiO3 perovskite, are calculated as a function of pressure up to …

Sodium iridium (V) oxide, NaIrO3, was synthesized by a high pressure solid state method
and recovered to ambient conditions. It is found to be isostructural with CaIrO3, the much …

Building and construction industries are at the same time the backbone and the driving force
of our modern society. Nearly all our technical infrastructure today is based on cement …
